How to configure Mail resource in Jboss 7.2 with a sample java client

This tutorial assumes that you have the following installed on your local system:

JBoss 7.2
eclipse to run a project
a mail server, can be gmail

In this page we will summarize how to configure a mail dataSource in Jboss and create a JavaEE6 client to send a sample email.

Configure Mail datasource in JBoss 7.2

Open standalone.xml

Search for the mail subsystem

<subsystem xmlns="urn:jboss:domain:mail:1.1"></subsystem>

Define a mail session

<mail-session jndi-name="java:/czetsuyaMail">
 <smtp-server outbound-socket-binding-ref="mail-smtp">
  <login name="[email protected]" password="secret"/>
 </smtp-server>
</mail-session>

Define an outbound socket we will create 2: smtp with port 587 (eg zimbra) and ssl with port 465 (for gmail). Search for socket-binding-group section and add the following lines: for Zimbra

<outbound-socket-binding name="mail-smtp">
 <remote-destination host="yourServer.net" port="587"/>
</outbound-socket-binding>

OR for gmail

<outbound-socket-binding name="mail-smtp-gmail">
 <remote-destination host="smtp.gmail.com" port="465"/>
</outbound-socket-binding>
In greater version of JBoss now Wildfly, username and password must now be specified in the smtp-server tag:
<smtp-server outbound-socket-binding-ref="mail-smtp-gmail" username="[email protected]" password="secret">
                </smtp-server>

Sample Client

package org.czetsuya.test;

import java.util.Date;

import javax.annotation.PostConstruct;
import javax.annotation.Resource;
import javax.ejb.Asynchronous;
import javax.ejb.Singleton;
import javax.ejb.Startup;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMessage.RecipientType;

@Startup
@Singleton
public class MailService {
 @Resource(lookup = "java:/czetsuyaMail")
 private Session mailSession;

 @PostConstruct
 private void init() throws AddressException, MessagingException {
  sendAsyncMessage("Test");
 }

 @Asynchronous
 private void sendAsyncMessage(String htmlMessage) throws AddressException,
   MessagingException {

  MimeMessage msg = new MimeMessage(mailSession);
  msg.setFrom(new InternetAddress("[email protected]"));
  msg.setSubject("Test");
  msg.setSentDate(new Date());
  msg.setContent(htmlMessage, "text/html");

  msg.setRecipient(RecipientType.TO, new InternetAddress(
    "[email protected]"));
  InternetAddress[] replytoAddress = { new InternetAddress(
    "[email protected]") };
  msg.setReplyTo(replytoAddress);

  Transport.send(msg);
 }
}

You can actually test with telnet if your port is open by executing this command in command prompt:

telnet server port
